Hi steve,
Thanks for the reply.I get unable to create application module exception when i try to use the business component in weblogic container version 5.1.I am using JDevelooper 3.1 version
public String ejbCreate(String productID,String name,String description,double basePrice) throws CreateException
System.out.println("****ejbCreate Called****");
this.productID = productID;
this.name = name;
this.description = description;
this.basePrice = basePrice;
Connection con = null;
PreparedStatement ps = null;
try {
String amName1 = "MyDev1.MyDev1Module";
String connStr = "jdbc:oracle:thin:scott/tiger@taipan:1521:web3";
Hashtable env = new Hashtable(2);
ApplicationModule appMod1 = null;
System.out.println("***First***");
env.put(Context.INITIAL_CONTEXT_FACTORY,JboContext.JBO_CONTEXT_FACTORY);
env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
System.out.println("***Second***");
javax.naming.Context ic = new InitialContext(env);
ApplicationModuleHome home1 = (ApplicationModuleHome)ic.lookup(amName1);
System.out.println("***Third***"+this.productID);
appMod1 = home1.create();
System.out.println("***Third1111***");
appMod1.getTransaction().connect(connStr);
System.out.println("*****Connected*****");
ViewObject vo = appMod1.findViewObject("BeanproductView");
System.out.println("*****Found View Product*****");
System.out.println("Row count ***"+vo.getEstimatedRowCount());
AttributeDef[] attr = vo.getAttributeDefs();
for(int i=0;i<attr.length;i++)
System.out.println("Attr Name --->"+attr.getColumnName());
return productID;
}catch(Exception e)
System.out.println(e);
//can check here whether the exception is due to unique constraint
}finally {
// cleanup(con, ps);
return null;
Steve,the error it gives me is unable to create the application module after
****setEntityContext called****
****ejbCreate Called****
